In recent years, gastroretentive drug delivery system (GRDDS) has gained researcher’s interest in the field of oral drug delivery. Various GRDDS approaches can be utilized to retain the dosage forms in the stomach and to release the drug slowly for an extended period of time. GRDDS can be used to prolong the residence time of delivery system in the stomach. This results in targeting of drug release at a specific site for the systemic or local effects. GRDDS can be used to overcome challenges associated with conventional oral dosage forms and to release the drug at a specific absorption site to improve bioavailability of particular drug substance. The challenges include fast gastric emptying of the dosage form which results in the poor bioavailability of the drug. Prolongation of the retention of drugs in stomach those having low solubility at high intestinal pH improves the solubility of drugs. GRDDS has proved to be effective in systemic actions as well as in local actions to treat gastric or duodenal ulcers. Local activity in the upper part of the small intestine can be obtained by improving the residence time of delivery system in the stomach. The system is useful for drugs which are unstable in the intestine or having a low solubility/permeability in the small intestine. Various GRDDS approaches include high density (sinking) systems, low-density (floating systems), mucoadhesive, expandable, unfoldable, superporous hydrogel systems, and magnetic systems.

Solid Oral Dosage Form

The purpose of any selected drug delivery system (DDS) is to deliver drug to target site and to get the desired drug concentration for effective therapy. The main purpose of designing controlled or sustained DDS is to decrease the frequency of dosing and maximizing its efficiency by confining the area of action of the drug to a selected region. It is well-identified that solid oral dosage form, particularly tablets, is the most satisfactory form of delivering medication. In addition, some new variations are emerging such as mini tabs which offer more formulation flexibility. Oral controlled release DDS are classified into two categories like single unit dosage forms which include tablets, capsules, and multiple-unit dosage forms include pellets, granules, or mini tablets. Mini tablets are a new development in solid dosage forms and more beneficial and great substitute for granules and pellets. Mini tablets defined as tablets which are having diameter <3 mm and promising patient friendly drug delivery system and more acceptable in small children’s and old age people as they are easy to swallow and offer therapeutic benefits such as manufactured relatively easy, dose and formulation flexibility, combination release pattern, coating, and less solvent requirement. Dose dumping and local irritation can be avoided using mini tablets. This review highlights the various advantages of mini tablets, manufacturing processes, formulation possibilities, and their challenges.

In Vivo Characterization

In the field of oral drug delivery system, a gastroretentive system is gaining popularity day by day. Numerous of research work and extensive literature are published in past few years on gastroretentive drug delivery system. It is the one of the best and appropriate approaches for increasing the residence time of drug in the stomach and diffuses drug slowly in the sustained manner which helps in the site-specific delivery of the drug as well also increases the bioavailability at site-specific of delivery. This helps in many challenges associated with conventional oral drug delivery system. Different ways are used for approaching gastroretention viz. swelling and expandable system, high-density system, magnetic system, bioadhesive system and buoyant system with or without gas generating agents. During data mining well in vitro characterization and in vivo characterization including gamma scintigraphic and MRI techniques are well established and reported. But, still, today in vivo characterization technique is major challenging for the researcher due to its limitation. The documented literature explains the use of animal models like beagle dogs, rabbits and human subjects for in vivo evaluation parameter but it leads to increase in variation that’s why this delivery system is limited in the market. This paper contains the latest literature compilation and various techniques used for gastroretention with its pros and cons. This review paper helps the researcher to take an overview of basics of gastroretentive drug delivery system and helps in understanding the basics of the system.Soni et al., International Current Pharmaceutical Journal, April 2018, 6(11): 81-91http://www.icpjonline.com/documents/Vol6Issue11/02.pdf

This review represents importance of mouth dissolving films as compared to other oral dosage forms. Fast dissolving oral drug delivery system are solid dosage form which disintegrate or dissolve within seconds when placed in the mouth without need of water or chewing. First developed fast dissolving dosage form in formulation and the rapid disintegrating properties were obtained through a special procedure or formulation modification, hence mouth dissolving film is proved to be better alternative in such cases. This fast dissolving drug delivery system is suited for the drugs which undergo high first pass metabolism and is used for improving bioavailability. Mouth dissolving film consists of thin oral strip; which release active ingredients immediately after uptake into oral cavity. In present investigation, an attempt has been made to develop oral fast dissolving film. Availability of larger surface area that leads to rapid disintegrating and dissolution in the oral cavity.

Fast Disintegrating Tablets

The Fast Dissolving Drug Delivery Systems sets a new benchmark was an expansion that came into existence in the early 1980’s and combat over the use of the different dosage form like tablets, suspension, syrups, capsules which are the other oral drug delivery systems. Fast Dissolving Drug Delivery System (FDTS)  has a major advantage over the conventional dosage forms since the drug gets rapidly disintegrated and dissolves in the saliva without the use of water .In spite of the downside lack of immediate onset of action; these oral dosage forms have valuable purposes such as self medication, increased patient compliance, ease of manufacturing and lack of pain. Hence Fast Disintegrating Tablets (FDTS) technology has been gaining importance now-a-days with wide variety of drugs serving many purposes. Fast Disintegrating Tablets (FDTS) has ever increased their demand in the last decade since they disintegrate in saliva in less than a minute that improved compliance in pediatrics and geriatric patients, who have difficulty in swallowing tablets or liquids. As fast dissolving tablet provide instantaneous disintegration after putting it on tongue, thereby rapid drug absorption and instantaneous bioavailability, whereas Fast dissolving oral films are used as practical alternative to FDTS. These films have a potential to deliver the drug systemically through intragastric, sublingual or buccal route of administration and also has been used for local action. In present review article different aspects of fast dissolving  tablets and films like method of preparations, latest technologies, evaluation parameters are discussed. This study will be useful for the researchers for their lab work.

Increasing Demand

The convenience of administration and improved patient compliance are important in the design of oral drug delivery system which remains the preferred route of drug delivery inspite of various disadvantages. Fast disintegrating tablets (FDTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. The popularity and usefulness of the formulation resulted in development of several FDT technologies. These techniques render the disintegration of tablet rapidly and dissolve in mouth in five seconds without chewing and the need of water which is advantageous mainly for pediatrics, geriatrics and patients having difficulty in swallowing tablets and capsules. Formulation of a convenient dosage form for administration, by considering swallowing difficulty and poor patient compliance, leads to development of orally disintegrating tablets. Conventional preparation methods are spray drying, freeze drying, direct compression, Molding, and sublimation while new technologies have been developed for the production of orodispersible tablets.
